SHAFT OR WELL LINING.

Application led October 7, 1912.

To all whom it may concern Bc it known that l, MARCEL GILLIEAUX, engineer, a subject of Belgium, and resident of Liege, in the Kingdom of Belgium, have invented a certain new and useful Improvement in Shaft or l/Vell Linings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings and to letters or figures of reference marked thereon, which form a part of this specification.

rfhis invention has for its object the production of structures of masonry which are supported from above and more particularly to linings for shafts, wells and the like, but may also be utilized for other purposes, for instance for making walls, chimneys and the like, where the masonry is to be carried by the upper course.

rl`he invention will now be more particularly described with reference to its application to lining shafts and the like.

rlhe construction is of a character in which the building proceeds from the top downward utilizing blocks which engage each other by means of hook like flanges. In accordance with this invention the lining elements are provided at their upper and lower ends on opposite faces with recesses forming hook like flanges. The recesses in one element correspond in depth to the thickness to the hook-shaped flanges of the other element whereby the interengagement of said flanges produces a smooth unobstructed surface on the inside of the construction which prevents any danger of articles passing through said tubular structure becoming engaged with projecting ledges.

Referring to the accompanying drawings: Figure l is a vertical section of a well lining, on the line C-D of Fig. 2; Fig. 2 is a horizontal section on the line A-B of Fig. l. Fig. 3 is a vertical section of a shaft or well lining according to another form of construction. Fig. 4 is an enlarged detail vertical section showing the ring 6 in operative position.

The shaft or well lining shown in Figs. 1 and 2 is made of flanged bricks l, at the upper end of which a horizontal recess and a rib or flange Q are formed so as to produce an externally directed hook. The

lower end of each brick 1 is also similarly formed. The horizontal rib here provided,

however, forms an inwardly directed hook.

The edges of these flanged bricks are rabbcted so as to fit together as shown in Fig. 2.

The construction of the lining or tubing is effected by suspending the first course of bricks by their hooks 2 in a ring 5, which forms the mouth of the well. Vtlhen the ground has been excavated to the depth of a second course of bricks, the hooks 2 of this second course of bricks are engaged in the hooks 3 of the first course. The bricks of the various courses preferably break joint.

In order to hold the separate flanged bricks in correct positions and to use them together as a coherent whole, an iron stillening ring 6 (Fig. l) is located in the lower hooked recess, after each course of bricks has been laid. ln Fig. 4 is shown the stiffening ring G fitting in the recess.

Vhen a number of courses of bricks have been interengaged, the further construction of the shaft or the like is temporarily suspended. rl`he interstice 7 between the last laid course of bricks and the wall of the shaft is filled up and packed with wood, stones and the like. Cement or concrete is then poured into the annular interstice between the already formed section of shaft and the ground, and it is allowed to set. When this has taken place the lining is integral with the surrounding ground and also the bricks of the various courses are firmly combined with one another. rThe further construction of the shaft can then be proceeded with without fear that the finished part of the shaft will be exposed to too great a tension stress by fresh courses of bricks being suspended thereon.

In order to facilitate the running in of the cement or concrete, apertures 8 may be provided in the bricks.

Under certain circumstances the second form of construction of the invention illustrated in Fig. 3 may be selected, in so far as it relates to shaft tubings. This form of construction is characterized by the use of bearing rings 9 and rods l0 in combination with the construction hitherto employed. rlhe bearing rings 9 in this case replace the stiffening rings 6 (Fig. l). When the cement is run in between the lining and the ground the bearing rings 9 may also serve for forming the lower seal between these parts.

Claim A shaft lining composed of a plurality of courses each divided vinto a series of lining); elements by plane surfaces which are parallel to the direction of the aXis of the 1G to those Von the other face, said hooks having recesses at the base of their engaging* faces to receive the heads of the hooks of adjacent elements, said recesses and hooks corresponding in Width.

In testimony whereof I affix my signature in presence of two Witnesses.
